Specification of Letters Patent.

Application flied August 24. 1914. Serial No. 858.230.

-cago, in the county of Cook and State of Illinois, have inventedcertain new and use ful Improvements in RaihAnchors, of which thefollmving is a specification.

llly invention relates to a device forpreventing the longitudinal creepof railroad rails, these devices being commonly called rail anchors,rail stays or anti-creepers, and particularly to a device in which oneor preferably both of the elements constituting the railclainp areresilient and are strained by the application of the device to the rail,so as to resist a retrograde movement as between the elements, tendingto loosen the grip of the device on the rail and hence diminish itsholding power. A rail anchor is subjected not only to the forward stresscaused by the creeping tendency of the rail, but also to vibration andto certain forces which operate at times in the direction contrary tothe forward creep of the rail, tendingto more the device away from thetie against which it is abutting and to loosen the grip of the partsbetween themselves and upon the rail. Unequal expansion and contractionof the rail and parts of the anchor, due to tempera'tnre changes, alsotend to destroy, unless checked, the holding power of the device.

The primary object of my invention is to provide a rail anchorcomprising a plurality of co-engaging elements which together grip therail, fpr example, the base flange thereof, and are so constructed andarranged that the forward creep of the rail produces a positive wed ingaction between the ele ments, where W said tendency to creep is selfchecked, one or both of the elements being resilient and strained byapplication of the device .to the rail so that vibration and shrinkageof metal due to temperature changes is absorbed and any tendency whichthe parts of the device may have toward a loosening or retrograderelative movement is prevented.

A further object of the in ventionis to provide a rail anchor which willbe inexpensive to manufacture, strong and durable and, at the same time,light in weight. -Weight is an important consideration as well in thecost of tr:ms n)rtat|on as Ill cost of manufacture.

The invention is illust1-=- oil in certain pre-' ferred embodiments inthe accompanying drawings, whercin Figure l is a sectional elevation, ofa rail anchor constructed in accordance with the invention shown asapplied to a rail, the view looking toward the tie against which thedevice is abutted.

Fig. 2 is a side elevation of the tie abutting element of the device,shown in the position which it assumesbefore the other element, theyoke, is put in place;

Like characters of reference designate like parts in the several figuresof the drawings.

Referring to the drawings, A designates a. railroa1l 1'ail and B one ofthe cross ties on which the rail is supported.

The rail anchor illustrated in Figs. 1 to 6 inclusive, consists of twoco-engaging elements. :1 tie abutting element C and a. yoke I). The tieabutting element C is in the form of a plate adapted to bear against thecross tie B and provided with 11.- tongue E preferably formed at itsouter end with an upward bend F. This element is preferably made ofsheet metal, sheet steel, for example. and the tongue is formed with atapered depression (I eonstituting in ell'eeta wedge.

lhe yoke element I) is adapted to extend around the base of the rail andthe tongue I: lying under'said rail base. -'l'he yoke is preferablyformed at the middle with a bend or indentation II and at one end withgrooves I for the applieation ot' a elaw bar.

ln applying the deviee to a rail. the tie abutting mem er t is plaeedunder the rail base against the tie. as shown in Fig. 2. The yoke isslipped under the. rail and around the tongue I) so that it assumes theposition shown in Fig. (3. The reressed end of the yoke is then engagedby a elaw bar .1; and is raised and at the same time l'orred toward therail into the position shown in Figs. 1 and I). This bends the part otthe tongue beyond or backward of the wedge t as best shown in Fig. I).The yoke may then be driven up the wedge (l toward the tie as 't':\ asmay be neeessary to obtain a seeure hold on the rail 'ith the parts olithe deviee in this position a wedge (i opposes the further movement otthe yoke toward the tim against whieh. it will he understood. the otherelement bears. forward rreep ot' the 'ail. whieh is imparted to the yokeI). produees a positive wedging aetion between the elements of theanehor that inereases the grip of the deviee on the rail so that theereeping movement is self eheeked. ()n the other hand. any retrogrademovel'neut of the yoke I) is eheeked by the downward slope of the outerend of the tongue I) resulting from the bending of the tongue. Theelastie relation between the two elements absorbs vibration and slightshrinkages of metal due to tempe 'ature ehanges. ll] order to facilitatethe applieation of the yoke. the end provided with the claw bar reeess Imay be formed-with a ram surfare K whieh rides over the edge ol the railbase. .\s a matter of l'aet. it would be possibl to apply thedevieewithout the use of :relaw bar. in whieh ease the reeess I might.be omitted.

In I igs. T to 1. 'inelusive. I have shown an author consistingpreferably. though not neeessarily. of two parts ('onstrneted likethoseot' the anehor just d-eserihed exeept that the yoke member ismodified so that one of its jaws will take a erainping or biting hold onthe rail and the other a \vedging grip when the deviee is in operativeposition. 'hen so eonstrueted the yoke will move forwardly with the railwhen the latter ereeps. It is funetiona-lly part of the rail. Fig. 7shows the position of the yoke when tirst applied to the rail. Fig. Hshows the elements of the anchor in their operative position. The yokedesignated I) is formed at one end with a bend (I so that when the yokeis adjusted to its position on the rail base the jaw on this end takesthe desired eramping grip on the lt-l L'(' of the rail base. may' eformed with a bearing 1/ tor the under surt'a're ot' the opposite edgeof the rail base. .\.s the surfare rl" of the yoke has the slope of theupper face of the rail base the transverse movement of the yoke inadjusting it to its tinal position gives it a wedging grip' on the edgeof the ail base at this 'ide. I

ln Figs. 10 aml 1t I-have shown a rail anehor eonstrneted upon the sameprinciples but in whieh the tie abutting member is strlietnrallyditt'erent. Ihe yoke member here designated I) may be substantially thewill! a the yoke member I heretofore deseribed. The tie abutting memberI, is made of rolled tapered stoek so that the tongue M is thiekest nearthe tie abutting plate'and thins down toward its extremities. 'hen thedeviee is applied to the rail. the thin t'lexihle end of the tongue isbent and the same result obtained as in the other form of the invention;that is. the forward movement ot' the yoke is eheeked by a positivewedging aetion between the yoke-and the" :tongue M while the movement ofthe yoke away from the tie is eherked by the bent end of the tongue.

While I have shown and deseribed the invention in eertain preferredemhmlilnents. further moditieations might be made without departure fromtheprineiples of the invention. 'lheretore I do not wish to-beunderstood as limiting the invention to the partieular eonstruetions.arrangements and deviees shown and deserilied exeept so far as the sameare speeitieally made limitations in eertain of the elaims herein.
